Chemical dosing system design and install - Diary Food Processing Plant
Background
Stainless Designs recently partnered with a leading cheese manufacturer to design and install a precision chemical dosing system that’s helping them streamline their sanitation processes, ensure consistent product quality, and meet strict industry compliance standards.
As one of the largest diary manufacturers in the world, their plant required an accurate, safe and maintainable chemical dosing system to safely automate the cleaning in place [CIP] of their plant’s membrane system.
The Challenge
Manual dosing of chemicals was leading to inconsistencies, potential overuse of chemicals, and increased operational risk to personnel and equipment.
Membranes are very sensitive pieces of equipment that inaccurate doses of high-strength chemical solutions can damage. Therefore, it was critical that our system accurately dosed volumes.
The chemicals are supplied in a concentrated state and must be diluted in the plant. High chemical resistance stainless steel pipework and equipment was critical to prevent corrosion in our dosing system.
The Solution
The Stainless team delivered a fully automated chemical dosing system tailored to their plant’s specific process requirements. This included:
• Accurate, repeatable dosing for cleaning and sanitation
• Real-time monitoring and control
• A CIP (Clean-In-Place) system with PLC sequence logic, which requires minimal operator involvement and will look after itself.
• Installation planned and executed to minimise plant downtime and impact on production.
• The design, fabrication and supply of two self-contained chemical storage cabinets.
Results
Improved chemical dosing accuracy. Accurate up to 0.5% of dosed volume.
Reduced the need for constant operator supervision of plant down to once per shift.
Enhanced safety and compliance by preventing concentrated chemical handling.
Decreased plant downtime by allowing consistent automated CIP (Clean-In-Place) washes increasing membrane plant throughput.
